Is there any use of canvas and svg in today's pages?

Answer 1

Strakoš There exist frameworks for working with canvas, or you can write most needed tasks yourself. Canvas are used when simple image won't do, i.e. you need to dynamically draw a graph.
SVG images are smaller in file size, so it's used to make websites load faster. Another boon is that SVGs scale, so you can reuse them at different sizes instead of having same image copy at 12px, 16px, 18px, 32px and 64px

Answer 2

Anything involving graphics.
